Abstract
The invention discloses a variable-stroke air cylinder piston of an air cylinder type internal combustion engine. When an engine piston operates at the suction stroke, a crankshaft drives a connecting rod, the connecting rod drives the piston, and a shaft of the connecting rod slides to the far end of a long hole of the piston to drive the piston to work under the action of negative pressure of gas in the air cylinder, so the length of the connecting rod is increased; when the piston operates at the compression stroke or power stroke, the crankshaft pushes the connecting rod or the piston pushes the connecting rod under the action of positive pressure of the gas in the air cylinder, the shaft of the connecting rod slides to the near end of the long hole of the piston, and the connecting rod recovers to the original length, so compared with the power stroke, the suction stroke of the engine is relatively reduced, and more pressure of expanded air of the engine after combustion each time is converted into the power by the method. The piston has the advantages and beneficial effects that the fuel consumption is little, the power efficiency is high, and the like.
Description
Technical field
The present invention relates to a kind of fuel utilization efficiency taking raising cylinder type explosive motor as object, carry out is for design and the improvement of the mechanical field of its cylinder piston structure.Thereby design a kind of cylinder type explosive motor route-variable cylinder piston.
Background technique
That general existing explosive motor has is air-breathing, compression, acting, an exhaust four-stroke, air completes air-breathing and compression stroke by piston, its volume is compressed several times to tens times and same fuel mix, when it is lighted after outburst, its volume can expand tens times on original basis again, and the gas push expanding like this promotes piston movement acting.Because the piston of general existing explosive motor is in journeys such as the working stroke of air-breathing, acting, exhaust, compression are all, the air pressure that its expanding gas produces can only some for acting, remaining,, by the consumption such as baffler, outlet pipe, has then emitted.Just think: when engine operation, in cylinder, after the expansion of gaseous combustion each time, if cylinder piston is air-breathing and the stroke of acting is X, the exploded gas middle pressure expanding in cylinder is 1, the acting of promotion piston is 100% words; If piston working stroke is 2X, though cylinder combustion explosive gas pressure is reduced to 50%, acting increases by 50%; When piston working stroke is 3X, cylinder combustion explosive gas pressure is reduced to 33%, and acting increases again 33%; When piston working stroke is 4X, cylinder combustion explosive gas pressure is reduced to 25%, and acting increases again 25%; Piston working stroke increases by 3 times like this, total acting amount=100%+50%+33%+25%=208%.Therefore the present invention can be designed to: large several times of the stroke ratio suction stroke of the part that the air-breathing stroke of piston is working stroke or piston acting, the gas pressure expanding after burning each time can be changed into acting more by this approach, realize explosive motor effect and be doubled and redoubled.
Summary of the invention
The present invention is to improve explosive motor fuel utilization efficiency as object, adopt a kind of cylinder type explosive motor route-variable cylinder piston taking increase acting with the ratio of suction stroke as improvement means, the mechanical field carrying out zero, the design of accessory structure and functional part.
1. a cylinder type explosive motor route-variable cylinder piston 1, it is characterized in that: connecting rod is connected with piston by the slotted hole 1a that is located at upper piston with the coupling shaft of piston, the coupling shaft of connecting rod also can be free to slide along slotted hole 1a in the slotted hole 1a of piston except rotatable, wherein the distance of the center of circle, slotted hole 1a two ends on piston is called route-variable=E, when engine piston during in air-breathing work bent axle pull connecting rod, connecting rod drives piston, due to gas negative pressure effect in cylinder, pitman shaft slippage could drive its work to the far-end of slotted hole on piston, be equivalent to extend the length of connecting rod, when piston carry out compression work or acting when work due to cylinder in gas positive pressure effect, bent axle promotes connecting rod or piston promotes connecting rod, pitman shaft slippage is to the near-end on piston slotted hole, and connecting rod recovers original length, thus realize motor suction stroke than working stroke than relatively reducing.Because coupling shaft carrys out back rotation and slides piston is slided and exerted an influence in the slotted hole 1a of piston, therefore establish slip anti-deflection device 1b to eliminate it on cylinder piston.
Wherein: logical relation between route-variable=E and the parameter of cylinder type explosive motor:
Compression ratio=(A+D-E)/A;
Cylinder displacement=(A+D) * R*R*3.14;
Cylinder gettering quantity=(A+D-E) * R*R*3.14;
Air displacement is called row with the ratio of gettering quantity and inhales ratio=A+D/ (A+D-E).
Wherein: A is the distance between piston gas-pressing surface and the compression afterwards of cylinder top; D is the swing diameter of axis; R is circle radius in cylinder.
